3 Claims.

The present invention relates to new and useful improvements in refrigerant condensing devices and has for its primary object to provide,

in a manner as hereinafter set forth, an appa-m ratus of this character embodying a novel construction, combination and arrangement of parts through the medium of which water may be utilized as the cooling medium in an economical and satisfactory manner.

Other objects of the invention are to provide a refrigerant condensing apparatus of the aforementioned character which will be comparatively simple in construction, strong, durable, reliable in operation, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specifica.- tion, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and whereinz Figure 1 is a View in side elevation of an apparatus constructed in accordance with the present invention with portions broken away in section.

Figure 2 is a top plan view of the invention, portion only of the cover being shown. Figure 3 is a view in end elevation of the upper portion of the apparatus.

Referring now to the drawings in detail, it

will be seen that the embodiment of the invention which has been illustrated comprises a container I which is mounted in a suitable supporting frame 2.

At one end, the frame 2 is formed to provide a platform 3, the purpose of which will be presently set forth. The container at 4, with water.

is adapted to be lled to the desired level, as The water may be received Mounted on the platform 3 is an electric motor 1. The adjacent end of ther container I has formed therein an opening 8 from which an annulus 9 projects.

A shaft I0 from the motor extends through the opening 8 into the container I and has fixed on its inner end portion a grooved pulley II.

Trained over the pulley II and depending loosely therefrom into the water is an endless agitating and elevating chain I2.

A fan I3 is fixed on an intermediate portion of the motor shaft I0 for operation in the annulus .The container I includes a cover I4 having formed in the end portion thereof which is remote from the opening 8 av plurality of air-discharge or outlet openings I5, as illustrated to advantage in Figures 1 and 2 of the drawings. The reference numeral I6 designates a condensing unit which is mounted vertically in the con-y tainer I. Inlet and outlet pipes Il and I8, respectively, are connected to the upper and lower portions of the condenser unit I6.

It is thought that the operation of the invention will be readily apparent from a consideration of the foregoing, particularly to those skilled in the art to which the apparatus pertains. The refrigerant in gas form enters the upper portion of the condenser unit I6 from the usual compressor. The refrigerant is condensed in the unit I6 and flows to the bottom thereof and is discharged through the pipeV I8. With the electric motor 'I in operation, water is agitated and picked up bythe elevating chain I8. This water is blown by the fan I3 against the unit I6 and against one end of the container I. This water then returns by gravity to the lower portion of the container I to be reused. It will be. observedv that the construction and arrangement is such that substantially the only loss of water that is sustained is by evaporation. The air escapes from the container I through the discharge openings I5. The container I may be provided with a suitable drain I9.

It is believed that the many advantages of a refrigerant condensing apparatus constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the inven- Ation as claimed. What is claimed is:-

1. A refrigerant condensing apparatus of the class described comprising, in combination, a container for the reception of water, a supporting frame for the containensaid supporting frame including a platform projecting beyond the container, said container having an air inlet opening therein adjacent the platform, an annulus projecting from. the 4container aroundthe air inlet opening, said container comprising a cover having air outlet openings therein at a point remote from the air inlet opening, a condensing unit mounted vertically in the container between the air Vinlet and outlet openings, an electric motor mounted on the platform, a shaft operatively connected to the motor and projecting therefrom into the container, a grooved pulley xed on the inner end portion of the shaft, an endless chain trained over the pulley and depending loosely therefrom into the water, said chain constituting means for agitating and elevating the water, and a fan fixed on the shaft and operable in the annulus for blowing the elevated water against the condensing unit` 2. A refrigerant condensing apparatus comprising, in combination, a container for the reception of a liquid, a condensing unit mounted in said container, endless conveying means operable in the container for elevating the liquid,
